I keep getting an error when trying to downgrade that the apploader will not work with my devices software 5.0.191. Do I need to have DDM 5.0 or will DDM 4.6 work to downgrade? Downloading 5.0 now so I may answer my own question.

Help. Trying to downgrade from 5.0.0.190 to 4.6.0.301.
I wiped. Now each time I try and load new system my bold reboots when the apploader trys to connect. The boot screen is still BB OS 5.0 splash.
Have tried numerous methods but will not load.
ANY suggestions? THANKS
